Copper(II) stearate is a metal-organic compound, a salt of copper and stearic acid with the formula Cu(C17H35COO)2. [2] [3] The compound is classified as a metallic soap, i.e. a metal derivative of a fatty acid.
Exchange reaction of sodium stearate and copper sulfate: [4] [5]
Copper(II) stearate forms a blue-green amorphous substance [6] similar to plasticine both in appearance and touch.
Insoluble in water, ethanol, or ether; soluble in pyridine. [7]
The compound is stable and non-reactive under normal conditions. [8]
When trying to ignite, copper stearate first melts and then begins to burn with a green (at the base) flame, then it quickly turns black due to the formation of cupric oxide:
The compound is used in the production of antifouling paint and varnish materials.
Also used as a component in casting bronze sculptures. [9]
Also applies as a catalyst for the decomposition of hydroperoxides. [10]
